Abstract:
There is provided mechanisms for polarized reception of reference signals. A method is performed by a terminal device. The terminal device is equipped with an antenna array having dual-polarized antenna elements. The antenna array is connected to a baseband chain in the terminal device. The method comprises receiving, during a beam management procedure with a TRP, two reference signals transmitted in one OFDM symbol each from the same TRP port within a slot. The two reference signals are received using a filter with a first polarization for a first of the two reference signals and with a second polarization for a second of the two reference signals. The second polarization is orthogonal to the first polarization.
